Types of Wine. Wines can be grouped into the six primary categories: white wines, red wines, rosÃ© wines, sparkling wines, dessert wines and fortified wines. White wines are wines that contain little or no red pigmentation. These wines are almost always made from white grapes, but can be made from black grapes as well.
pisgahchemist. HCl(aq) exists as hydrated H+ and Cl-ions. KBr is a network solid with bonds with relatively high ionic character (68% ionic character). The remainder of the compounds have greater covalent character including CuO and CuS.CuO bonds have 45% ionic character, CuS bonds are even less.Don't be suckered into the notion that metal-nonmetal bonds are ionic.isgahchemist.

248 Cm has been produced only in milligram amounts. Curium is similar in some regards to gadolinium, its rare earth homolog, but it has a more complex crystal structure. Curium metal is lustrous, malleable, silver in color, chemically reactive, and is more electropositive than aluminum. Curium metal exist in two crystal forms, a double hexagonal close packed (dhcp) and a high temperature face-centered cubic close packed (fcc) structure. Metallic curium dissolves rapidly in dilute acid to form Cm(III) solutions. Curium metal surfaces rapidly oxidize in air to form a thin film possibly starting out as CmO, Oxidation then progressing to Cm 2 O 3, and eventually to form stable CmO 2. Note however that the formation of divalent compounds of curium such as CmO have never been observed in bulk form.
